Patent GB-2118985-A (GB)
Title: Gasket material and method of manufacture thereof
Inventor: TRACY DOUGLAS H
IPC: F16J15/10
Filed: 1983-01-27
Abstract: A soft sheet gasket material comprises 50 to 75% by weight monoclinic mica (Muscovite) and 2 to 20% cellulosic fibers, and an organic binder. It may contain fillers, pigments, curatives and processing agents but is free of asbestos. It can be made by adding the micra particles to an aqueous slurry of the fibres after beating, and the material is then formed on paper-making equipment. This gasket material has properties comparable to those of asbestos- containing materials heretofore used without the health problems associated with such materials.
Patent GB-2135828-A (GB)
Title: A monopulse radar antenna
Inventor: WATSON BRIAN WALTER
IPC: G01S13/44
Filed: 1983-02-24
Abstract: The antenna comprises an array of radiating elements 32 arranged in pairs symmetrically about the bore-sight axis 38. Each of four hybrid rings 40 form the sum and difference of the signals received by a symmetrically situated pair of elements 32 in an inner set of eight elements 32. The outputs of the hybrid rings are summed and applied to a sum output line 46a and a difference output line 46b. The signals received by the set of four elements 32 at each end of the array are summed separately and applied to a fifth hybrid ring 50. The outputs of the hybrid ring 50 and the output lines 46a, 46b are combined and fed to a sum port 34a and a difference port 34b. For generating a secondary surveillance control pattern, a directional coupler 66 divides power at a control port 67 in opposite phases between a central control element 64 and the divider 56 of the feed network. The main interrogation is effected by pulsing the sum port 34a; the coupler 66 routes this power only to the divider 56. <IMAGE>

Patent GB-2143894-A (GB)
Title: Internal combustion engine ignition control
Inventor: CAMERON EWEN
IPC: F02B1/04
Filed: 1983-07-19
Abstract: The igniting element X is positioned near one end of a primary duct A open to the combustion chamber at the other end and of low impedance to gas flow over the whole engine speed range. This duct is continued as a secondary duct or ducts B of broadly equal cross section area to communicate with the combustion chamber. The ducts B have low impedance to gas flow at low and starting engine speeds but with an impedance to gas flow which is high compared to the impedance of the primary duct at higher engine speeds. Residual non-ignitable gas held in the ducts A and B is compressed by inflow of combustible mixture both via the primary and secondary duct sections during the compression stroke. At higher engine speeds the combustible mixture reaches the element X earlier in the compression stroke to provide more advanced ignition. The element X may be a spark plug, catalytic surface or an electrically or combustion heated glow plug. <IMAGE>

Title: Paper feed mechanism for rotary die cutter
Inventor: YON WILLIAM S
IPC: B65H23/188
Filed: 1983-10-27
Abstract: In a rotary die cutter or printer scrap between treated areas is eliminated through a "net pull-back" of the web 10 during the portion of the cycle when the web is free of the treatment means. The impression roll 30 is maintained at constant peripheral velocity and the web 10, while engaged by the die on said roll 30, travels at the same velocity. As the trailing edge of the die approaches the nip between the rolls 30, 32, one or both of the rolls 24, 26 driven by the web 10, is clutched into a cam mechanism for positive driving at a constant velocity equal to the velocity of the web 10, and this condition continues until the die releases the web 10 beyond the aligned centres of the rolls 30, 32 whereupon the web 10 comes under exclusive control of the rolls 24, 26. The cam-controlled velocity of the rolls 24, 26 and web 10 is then decreased to zero and is maintained at zero for a time dependent upon the peripheral distance between the die trailing edge and die leading edge. The rolls 24, 26 are then driven in a reverse direction for a fixed distance and then accelerated forward to the peripheral velocity of the roll 30, at which point the leading edge of the die engages the web 10 at the exact point of disengagement of the trailing edge of the die on the previous cycle. The clutch is subsequently disengaged. <IMAGE>

Patent GB-2175759-A (GB)
Title: Rechargeable battery systems
Inventor: MUDFORD JOHN NEIL
IPC: H02J7/00
Filed: 1985-06-01
Abstract: The system periodically subjects the battery 12 to a heavy discharge to prevent the battery retaining a memory of a long series of short discharges and charges, which memory would prevent it from supplying power over a longer period. The heavy discharge may be initiated by a timer, e.g. at one month intervals. Alternatively, a counter 22 may be stepped for each charging operation, the counter 22 giving a signal on a line 30 or 26 at a preset count to turn on a transistor 34 to discharge the battery 12 via a resistor 36 until a predetermined battery voltage is sensed. The counter signal on line 26 may alternatively cause the battery to be discharged by cycling on arithmetic logic unit through a predetermined program (Fig. 3) to simulate normal use of the apparatus 1, the logic unit being part of an electronic circuit 10 normally powered by battery 12. The discharge operation may be inhibited until valuable data in a memory (50), (Fig. 2), of circuit 10 has been read into a central computer. The apparatus 1 may be a portable electronic clock used in an electronic guard patrol system. <IMAGE>

Title: Caster mounting apparatus
Inventor: KREEGER ELSMER W
IPC: B60B33/00
Filed: 1985-07-12
Abstract: Casters 14 are detachably mounted upon the underside of the frame 10 of a dolly by means of a single bolt 36. The caster is provided with a flat, horizontally disposed mounting plate 22 which underlies and bears against a horizontal surface defined by the lower edges of ribs 17 and surrounded by a wall 18 on the bottom of the frame. The mounting plate can be vertically moved into face-to-face engagement with the horizontal surface when in a first angular orientation and then rotated about a vertical axis to a second angular orientation in which webs 30, 32, 34 spaced below the horizontal surface underlie portions of the plate 22 to retain it against vertical separation from the frame. A single bolt detachably retains the plate against rotation from this last position. <IMAGE>

Abstract: 851,961. Registering and recording working time of machines. TELEFONAKTIEBOLAGET L. M. ERICSSON. March 26,1959 [March 26, 1958], No. 10712/59. Class 106 (4). Apparatus for recording the time during which a metal machine tool works a metal workpiece comprises recording apparatus 11 actuated by a relay 6 which is excited by potential derived from the thermo-junction between the tool and workpiece. Alternatively, a counter 12 may register minute pulses derived from a switch 15 controlled by a cam 14 driven by a synchronous motor 13 operating during the periods that the switch 7 is closed by the relay 6. An amplifier 5 may be required in the relay circuit. When the tool rotates as in a lathe, the thermal potential can be picked up by a brush or may be tapped at a terminal in the machine base as near the contact surface between tool and workpiece as possible. Records may be made on a single time-driven strip 10 of the working of several machine tools.
